Help make the New Year's Day 10k a great event

We will have 650+ runners entered for the Start Fitness New Year's Day 10k and 3k and really want to put a great event on for them, so if you can spare some time to help on 1 January 2018 in Hyde Park, please sign up. The race starts at a sociable time, so wouldn’t require too much of an early start. Please do remember that the club is run entirely by volunteers and events such as this cannot happen without your help. This is your opportunity to give something back to the club. Sign up to help
